FRUIT JAR.

Application filed. May 20, 1924. Serial No. 714,579.

` To all whom t may concern:

Be it known that I, SIDMooR SAMUEL SAGER, a citizen of the Dominion of Canada, a resident of the city of Buffalo, in the county of Erie, in the State of New York, in the United States of America, have invented certain new' and useful Improvements in Fruit J ars, of which the following is the specification. n

My invention relates to improvements in fruit j ars, and the object of the invention is to provide a suitable container of the vacuum type for fruit, vegetables and the like, wherein a pump for exhausting the air therefor can be used in conjunction therewith.

A further object is to devise a jar in which air can be readily admitted when it is desired to open the sealed jar.

A still further object is to devise a jar which will be simple in construction, and which can thus be readily manufactured.

lVith these and other objects in view, my invention consists of ajar constructed and arranged all as hereinafter more particularly described and illustrated in the accompanying vdrawing in which Fig. l is a vertical section through'a jar, constructed according to my invention, showing the cover thereon and the pump applied to the jar.

Fig. 2 is a plan view of the jar with the cover removed, and i Fig. 3 is a vertical section of the upper portion of a modified form of jar.

Like characters of reference indicate corresponding parts in the different views.

1 is the ar or container body which may be constructed of any suitable material. 2 is a single annular upwardly extending flange at the top of the ar, said flange being interrupted at one or more points to 'constitute an aperture or notch 3. 4 is a substantially horizontallyrextending' annular surface upon which the washer or sealing ring 5 is designed to rest. 6 is the jar cover having the depending annular flange 7 with a lower edge 8 of pref-V erably V-shape in cross section which is designed to co-act with the ring 5 when the jar is sealed. 9`is a second substantially hor'- zontally extending annular surface in the vicinity of the top of the jar adapted to act as a seat for the ring 10 of the pump which is designed to rest thereon when the jar is being sealed,

The pump forms no part of the present invention, being shown merely to give a clear idea of the several parts of the container. n .j

In the form of the jar shown in Figures 1 and 2 it will be noted that the flange 2 is positioned at the inside .of the lip,and that the ring 5is prevented from inward distortion, being in Contact therewith, whereas in the modification illustrated in Figure 3 the flange 2 is deposed intermediately of the width of the lip. In the latter caseV the flange prevents outward distortion of the sealing ring 5 when such ring is compressed. In either case the flange 2 prevents the ring 5 being displaced during the sealing operation. l In the form of ar illustrated in Figures 1 and 2 the surface 9 constituting the seat for theppump ring 10 is positioned below the plane of the surface 4, and thus an annular shoulder 1l is formed which co-acts with the inner surface of such ringvlO, preventing its distortion during the pumping operation. In the modification the inner surface of the ring l() is in engagement with the outer surface of the flange 2 when the pump is applied to the jar lfor exhausting the air therefrom.

In opening the sealed jar a pin or other sharp instrumentis inserted under the sealing ring 5 into'the containerl, thus allow-y ing air to be admitted to such container, when the cover 6 can beremove'd. In Lthe the pin is first inserted under the ring 5, and then through the notch or aperture 3, whereas in modified form the pin is inserted through the exposed notch 3 and then under the ring 5. Y

In either case the same result is produced.

In order to make more comprehensive the uses of the various parts of my jar I will now describe the method of sealing the same.

The jar container is first filled with the desired material, the sealing ring being placed in position on the seat 4. The cover is then put in place so that theV-shaped lower edge of 8 of the flange 7 co-acts with the upper surface vof theV sealing ring 5. The pump, which may be of any suitable construction, but preferably that disclosed in my Canadian Patent Number v'220,402 issued July 4, 1922, is now applied to the container so that the ring 10 seats on the form of jar illustrated in Figures 1 and 2 j annular surface 9. The pump' is now operated to exhaust the air, and during the suction stroke the cover 6 of the jar is caused to be raised sufficiently to permit the escape of air from the container. On the down stroke the cover 6 is drawn down against the sealing ring 5 4due to the rareied condition of the air within the jar, thus preventing the replacement of air exhausted from within the container. The pump is operated until the required vacuum is obtained in the jar, when itis removed therefrom.

From the above description it will be seen that yI have devised a simple andI effective jar, particularly yfor use where itis desired to' remove the air from the ljar, and it is moreover an improvement on the jar covered by my Canadian Patent Number 205,096 in that the two concentric flanges described in such specification are replaced by a single annular flange, thus effecting a considerable improvement in construction. Likewise in my present form of jar the outer wall of the container is of substantially uniform diameter throughout its length, thus making for a jar of pleasing appearance.

What I claim as my invention is:

A container of the class described comprising a body portion having an annular surface constituting a sealing ring seat, a

sealing ring seated on the annular surface constituting its seat, and a cover havinga depending annular flange adapted to co-act with .the sealing ring, the body having a shoulder constituting a pump seat below the sealing ring seat and outside the exterior Aperiphery of the cover, whereby a pump may be applied to said jar for exhausting the air therefrom. y

In testimony whereof, I aflix my signature.
